All Metal Glock Competitor!? // Rock Island Armory STK100
The Rock Island Armory STK100 is a 9mm handgun featuring an aluminum frame with a 1911 grip angle, designed to be a competitor to Glock-style pistols. It offers compatibility with many Glock aftermarket parts, an optic-ready slide cut for Shield RMS footprint, and front and rear serrations. Initial impressions suggest good accuracy and manageable recoil, with potential for significant aftermarket support.
